An unhandled win32 exception occurred in explorer.exe [240]. Just-In-Time debugging this exception failed with the following error: No debugger has Just-In-Time debugging enabled. In Visual Studio, Just-In-Time debugging can be enabled from Tools/Options/Debugging/Just-In-Time.

If you did have Visual Studio installed, you could learn the values of registers and the offset from the nearest symbolic address within Explorer where it bombed - which would tell you - exactly nothing of value. Then you could poke around in memory, and probably learn... exactly nothing of value.

Explorer (EXPLORER.EXE) and Internet Explorer (IEXPLORE.EXE) share a great deal of code (in the form of DLLs) but are individual and distinct programs. Internet Explorer is typically installed in the Program Files files directory.

Internet Explorer is an application - you open and close it. Explorer is a core part of the operating system. There is a method to close Explorer, but when you do so, the taskbar and desktop icons vanish and Windows becomes unusable unless you are able to restart it again (I think the task manager can be used for this but I haven't needed to do this for a long time.)
